Viewing

Berkowski made the first solar eclipse photograph on July 28, 1851, also using the daguerrotype process, at the Royal Observatory in Königsberg, Prussia (now Kalinigrad in Russia). Berkowski, a local daguerrotypist whose first name was never published, observed at the Royal Observatory. A small 6-cm refracting telescope was attached to the 15.8-cm Fraunhofer heliometer and a 84-second exposure was taken shortly after the beginning of totality.
